This snake is found on trees and shrubs. 

 Although belonging to a nocturnal family, it is 

 often seen out in the daytime. When alarmed 

 the snake has a habit of opening its mouth and 

 stretching its lower jaw into the form ot a square, 

 which gives it a most threatening appearance. 



The up-country (hill) varieties are much 

 smaller than the low country ones. Of the two 

 hill varieties, one has green ventrals and the 

 other dark red ones. 



Dryophis Pulverulenttcs.
